Schematic for the MacBook Pro A1297, logic board 820-2390 with revision A, project K20, marked as a DVT1 build in the name. DVT means design validation test, so this is a pre-production drawing and some values or parts may differ from retail boards. Apple prints the 820 number on the logic board, making it the check to use before trusting the drawings. The PDF is used for tracing the power-up sequence, rail generation and signal paths when a board is dead, shorted or failing to charge.
